Spy video that captures what appears to be a heavily disguised 2015 Mustang prototype has been making the rounds on the web lately, and the best part is that it captures what certainly sounds like a V8.

I'm in agreement with Autoblog that most likely the new 'Stang will come with a version of the 5.0-liter Coyote V8 engine that's in the current Mustang GT. I'm also fine with that, because it's a badass engine that puts down 420 horsepower. It sure sounds like that engine in this video, but only God (and Ford) knows what's been done to the motor and exhaust tuning.

What do you think, Mustang experts? Does this sound like the real deal? I could definitely get used to that engine note if it is.
